SEAM-REENFORCING MACHINE.

Application filed December 22, 1923. Serial No. 682,294. i

To all 'whom t may concern.'

Be it known that I, Jniirns 1V. BRUNDAGE, a citizen of the United States, and resident of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Seam-Reenforcing Machines, of which the following is a specification. i Y i My present invention relates to improve'- ments in machines for reenforcing the seams of articles made of thin sheet rubber in the manner disclosed in Patent No. 1,458,801, dated June V12, 1923, and is designed more particularly for use in the manufacture of bag-like articles or containers, such for eX- ample as are used Jfor holding powder puffs' and the like.

The invention aims to provide a machine which will be simple, economical and efficient. and adapted to support the article in a proper manner during the seaming operation invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An embodiment of my invention is illustrated in the accompanying drawings in which z- Figure 1 is a side elevation of suoli a seam reenforcing machine.

Fig. 2 is an end view as seen from the left,

r 'Y Fig. 1.

drawings, the numeral 1 designates the drivev or operating vshaft journaled in suitable bearings in the base 2 of the machine, and carrying means by which it may be driven from any suitable prime mover (not shown) such as belt pulley 1a. This shaftyl carries a worm 11 which meshes with a worm or spiral gear 3 fast on a sleeve or quill shaft 4t which encloses a main shaft 5, sleeve 1 and shaft 5 being rotatably supported by the walls of the frame or housing' 6 sup aorted by the base 2, the housing being pre erably made in two parts (designated 6 and G respectively) 'for convenience of assembly,

. clutch member.

part G being bolted to the base and partl 6 to part G.

J ournaled in the upper part of the housing is a shaft 7 which is designed to operate the seaming roll in the manner hereinafter described, this shaft having loose thereon within the housing, a gear 8 which meshes with gear 3 above described. Gear 8 has fast thereon clutch part 9a which-is adapted to be engaged by a coacting clutch part 9" splined on the shaft and operated so as to automatically couple the gear to and uncouple it from the shaft at suitable intervals. My preferred manner of doing this is to provide a spring 10 encircling the shaft between clutch member 9b and a liXed abutment 7"L on the shaft, which spring tends normally to press the movable clutch member into clutching position, movement of the clutch member 9" in the opposite direction being effected by a shifter lever 11 having a suite able fork engaging an annular groove inthe The lever 11 has an intermediate portion fulcrumed upon a bracket 61 carried by the casing and its lower end is provided with an anti-friction roller 11n designed to coact with a cam 12 fast ony the sleeve or quill shaft l and having high and low faces 12 and 12b (see Fig.` 7) respec tively, each of which extends approximately 1800 of the circumference of the cam.

From this it will be seen that shaft 7 will be driven intermittently with proper intervals between the periods of rotation, which with the cam described will be of equal duration, though the relation of the drive period to that of rest may be varied according to the character of work by merely varying the respective areas of high and low parts of the cam.

The outer end of shaft Y is journaled in the overhanging end of a standard or bracket 13 supported from the base 2 and carries a sprocket 14- fast thereon which is geared by means of link belt 15 to sprocket 16 fast on shaft 17 journaled in the bearing portion 18" of an arm 18 (see Figs. 1` and 8) having a bifurcated portion fulcrumed at 18a on the standard or bracket 13. The shaft i 17 carries the seaming roller 19 which has a V-shaped peripheral groove and-is designed to coact with the seam supporting roller 20 mounted to rotate about a fixed axis. The arm 18V is acted upon by a compression spring 21 which causes the roller 19 to be pressed into contact with the supporting roller 2O with the required pressure to eliect the seaming operation. A chain slack takeup may be provided in the shape or' a roller 22 carried by the projecting portion 18 ot arm or lever 1,8.

These powder putt containers are of bag or pocket shape with a contracted mouth and it is necessary to support the roller Qt) in such a way that the supporting means ivill not interfere with the Walls or mouth ot the bag or container. To accomplish this I journal. the roller Q() upon one of the arms or a- U-shaped member' 22, the other arm ot which is tast on the projecting end of the shaft hereinbei'fore described. The. U- shaped portion ot' the bracket or the space between the arms is ot a depth equal to or greater than the length ot the container to be seamed, which permits the container to pass. doivir or envelop the supporting wheel 20 and arm 22 as the bottom of. the Contail er is approached and reached. It will be understood that the seaming ot one side ort the bag is starte l \vith the arm 22a in substantially horizontal position.. seaming rollers, drawing the seam between them, approach the bottom of the bag, it is necessary that the arm 22a shall. be swung downward until, as the bite ot the rollers reach the center ot the bottoni oli the bag or container, the arm 22a will be vertical, the reverse operation taking place as the rollers seam the opposite side of the bag.

To cause this arm to thus move in synchronism Withfthe action of theI seaming rollers, I provide the following described mechanism.

The sleeve or quill shalt et has fast thereon aan eccentric 23 which is connected by a strap and eccentric arm Q3 (see Figi. Wit-h a pin 2l fast on a gear segment 25 articulated on a fixedl pivot which may conveniently be the shaft 7. Gear segment 25, the teeth of Which act as a 1fach, meshes with a gear 26 fast on shaft and it will thus be seen that as the quill shaft rotatesv they gear segment 2 5 will beI oscillatedby the eccentric 23 and will in'ipa'rt an oscillating` movement to the shaft 5 and U-shapedsupport. 22

through an arc ot ISO", the mechanism beng so timed that with the arm 22? in horiiiontal; position, as` above described, at the time `vhen theroller 1.9 beginsits drive, thening of the seaming operation the: arm 22.1v would be 1n horizontal position pointing to.-

Wards the operator, at which time the edge As the or the seam is started between the seaming rollers. Asz the rollers travel over the seam and draw the container onto the arm, the said arm gradually swings. around until, when the rollers reach the opposite edge and the bag is complete, the carrying arm points away 'troni the operator and delivers the completely seamed bag. At this time the d-rive ot the pressing roller is interrupted and during its idle period the supporting arm 22 swings back to its orig" ialrposition ready to begin operation on a l shl bag or container.

Having thus described my invention, what I claim is:
